Description
Technical field
The present invention relates to a kind of natural water original position restoration of the ecosystem device, be particularly related to and be suitable for the original position restoration of the ecosystem device that lake and lake outlet road water body are gone in the lake, it utilizes artificial ecology microbial film based technique for in-situ remediation to eliminate organic pollutant, nitrogen and phosphorus in the natural water.
Background technology
Along with national cities and towns and plant-scale expansion, China's water pollution situation is quite serious, makes many rivers and lakes water body all be in serious pollutional condition, and still has the trend that continues aggravation.Main river course, the whole nation presents characteristics such as ecosystem fragility, contamination class is various, type is complete, and water body is in the moderate eutrophic state.How repairing the pollution of natural water effectively and solving the water eutrophication state is the problem that urgency is to be solved that China faces.
The bioremediation technology of natural pollution water body mainly adopts the microbial film in-situ techniques both at home and abroad at present, by absorption, conversion and the degraded of biological and microorganism, removes nitrogen, phosphorus and organic pollutant in the water body, reaches the purpose of repairing contaminated natural water.
Biomembrance process is a kind of method for biologically treating wastewater efficiently, widespread use in municipal sewage treatment.In bio-reactor, microorganism is adsorbed on the surface of carrier, forms one deck microbial film.In wastewater treatment process, organism and oxygen in the waste water enter microbial film, are decomposed by the cell on the microbial film.Organism in the waste water constantly is adsorbed on the microbial film, and the microorganism on the microbial film is decomposed these organism, and constantly metabolism, thereby reaches the purpose of Continuous Wastewater Treatment.Microbial film is owing to anchor on filtrate or the carrier, therefore long bacterium and the higher microorganism of growth time therein, this makes biomembrance process removing the organic denitrification dephosphorization function that has simultaneously, especially there is tangible decontamination effect improving in the river that is subjected to organism and ammonia and nitrogen pollution.In addition, on microbial film, also may occur thread fungus, wheel animalcule, nematode etc. in a large number, thereby the biomembrane purification ability is strengthened greatly.
Though biomembrance process has above-mentioned lot of advantages, yet effect was not desirable especially when the original position that is applied to natural water was repaired.This mainly is because in the contaminated natural water, dissolved oxygen lower (＜2 mg/L) and influenced microbial growths such as heterotrophic bacteria and nitrifier makes microorganism can not bring into play corresponding effect.In addition, in the treating processes, outer field microbial film can come off successively in position, and the microorganism that comes off has constituted secondary pollution to water body, has influenced water correction effect (existing original position restoration of the ecosystem apparatus and method have all been ignored this point).
Chinese invention patent ZL200610076417.1 discloses a kind of in-situ remediation ecologic reactor for water body, and it comprises rotation vegetation based system, rotating biological filler assembly, wind power driving system, hydrodynamic(al) microbial film rotating disk, pedestal etc.This device as nutritive medium, adopts water culture technique cultivation waterplant with eutrophication water, and by sun power photosynthesis, the fortified water plant is to the absorption and the conversion of nutritive medium, thereby reaches the purpose of nitrogen phosphorus equal size in the degradation water.Simultaneously, taking microorganism that the organism in the water is carried out high-intensity degraded removes.The deficiency of this device is, complexity is set, and running cost is higher, and does not solve the secondary pollution problem that dissolved oxygen is low and microorganism comes off and causes in the water body equally.
To sum up, prior art also can't fundamentally solve the river water body eutrophication problem with lower cost.
Summary of the invention
Technical problem to be solved by this invention is to overcome the deficiencies in the prior art, and a kind of simple in structure, running cost is low and the water body repairing effect is good natural water original position restoration of the ecosystem device is provided.
